Police responded Thursday to a Florida home where officials believe a woman was mauled and killed by her dog.

Lake County emergency medical services and Leesburg Fire Rescue requested police assistance on a medical call. Medical first responders entered the back of the home where Sonda Tyson, 66, was found dead, according to a release.

A person called 911 from the home and reported the victim was bleeding everywhere, had bite marks on her arms and the caller could see Tyson's bones.

Officials said they discovered a brindle pit bull mix, weighing about 100 pounds and covered in blood inside the home. They believe it is likely the reason for the victim’s injuries.
